The growth of plant roots and animal activity may result in .?
mechanical weathering
Mechanical Weathering?
In mechanical weathering, rocks are broken down into smaller pieces without changing their composition. Mechanical weathering is caused by freezing and thawing, release of pressure, plant growth, action of animals, and abrasion.
What are the main causes of crack growth in rocks overtime?
weathering and plant growth growing through and eventually causing a crack in the rock
Animal burrows dug in rock that let in water and air chemical or mechanical?
Plant growth is both a chemical and mechanical process. The roots secrete mild acids that dissolve minerals in rocks, and the plant's roots and stems can increase in size and force rocks apart inside cracks and crevices.
What type of weathering does plant cause?
Plants can cause mechanical weathering by growing into cracks in rocks and breaking them apart as their roots expand. They can also cause chemical weathering by releasing acids and other compounds that break down the minerals in rocks.
What are the four causes of mechanical weathering?
ice wedging pressure release plant root growth and abrasion
What kind of plant causes mechanical weathering of a rock?
any plant

What are the effects of mechanical weathering?
Freezing And Thawing, Release of Preserve,Actions of Animals,plant growth,abrasion
Is plant root growth mechanical weathering?
Because roots physically encompass and break down soil.
Is growth of plant roots mechanical or chemical weathering?
The growth of plant roots is more related to mechanical weathering. As roots grow and extend, they can exert pressure on rocks, causing them to break apart. This process helps in breaking down rocks into smaller pieces and enhancing soil formation.
Is moss chemical or mechanical weathering?
Moss is biological weathering, actually, because it involves a plant.
What are the main causes of crack growth in rocks overtime?
weathering and plant growth growing through and eventually causing a crack in the rock
Which of these are not Not a source pf mechanical weathering?
Precipitation (source of chemical weathering) Plant roots (source of chemical weathering) Freezing and thawing (source of mechanical weathering) Human activities (source of mechanical weathering)
What does the term mechanical weathering mean?
Mechanical or physical weathering is a process in which a rock is broken down into smaller pieces by factors such as water absorption or freezing and thawing. It can also be caused by plant root growth.
How does release of pressure affect mechanical weathering?
There are two main types of weathering: mechanical (also called 'physical') and chemical. Pressure release is a form of mechanical weathering. Pressure release usually occurs when rock that has been deeply buried, rises toward the surface due to the erosion of the mass of rock above it. Pressure release causes fractures and exfoliation in the depressurizing rock body. These fractures in the rock make it more susceptible to, and accelerate, other modes of mechanical weathering attack, such as freeze/thaw hydraulics and plant root growth.
